Abstract

Yellow curve: Pressure (cmH2O) on X-axis and Time (seconds) on Y-axis
Pink curve: Flow (L/sec) on X-axis and Time (seconds) on Y-axis
Green curve: Tidal volume (ml) on X-axis and Time (seconds) on Y-axis
Orange curve: Esophageal pressure (cmH2O) on X-axis and Time (seconds) on Y-axis
The blue arrows point to the inspiratory effort on flow and esophageal curves that is not followed by a breath
